Renault's Cyril Abiteboul has revealed that the French manufacturer aims to continue its ascent in the engine department as the company is preparing a completely new platform, including novel technology that has not yet been seen on the track.

Electrically controlled, hydraulic operated, much faster than only solenoid driven. The weight penalty is almost negligible and the benefits of faster VLIM control I think would be worth it. But eh, not my pumpy lump.

Surprised no one talks about the shape of the ports.

The height of cultivation is really nothing special. It is merely simplicity; the ability to express the utmost with the minimum. Mr.Lee

Modern electric actuators can have quicker reaction times and be more precise than hydraulic ones.

Aircraft are moving away from hydraulic actuation to electric for this very reason. (As well as reliability).

The cons are more expensive and still generally not providing as a force, neither of which is a factor in this application in F1.

Also as TC said, they don't need to be solenoidal action isn't the only way.
